SCAFFOLDING.

SPECIFICATION forming part of Letters Patent No. 470,032, dated March 1,1892. Application filed June 15, 1891. Serial No. 396,394. (No model.)

To all whom/ it may conccrn:

Beit known that LJAMEs ANDERsoN, a citizen of the United States,residing at Harrodsburg, in the county of Mercer and State of Kentucky,haveinvented certain new and useful Improvements in. Scatfolding; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improvement in scafiolding to be used byworkmen in the erection of buildings and is designed for use bycarpenters and others.

The invention has for its object to provide at a minimum expense ascaffolding which will be very durable and effective for carpenters andothers and maybe quickly adjusted and securely held in position whilelaying weather-boarding.

The invention will be fully understood from 'the following descriptionand claims when taken in connection with the annexcd drawings, in which-Fgure 1 is a viewin perspective of myimprovements, showing the sameapplied to a portion of the structure to be used by carpenters in layingweather-boarding. Fig. 2 is a sectional detail view of the same.

Referring by letter to said drawings, A indicates a portion of theframe-work of a house or other structure in the course of erection, andB indicates the corner posts or studding.

C indicates the weather-boarding of the structure.

D indicates the improved brackets. These brackets are composed of ahorizon tal branch a and two laterally-diverging 'legs b, secured attheir upper ends (Z to the outer end of the branch or bar a, so thatsaid ends d may project above the upper side of thebar a,as shown. Thelower ends of these legs b are pronged, as shown at c, so that they maytake into the Weather-boarding or wall beneath and sustain the branch orbar aV in a horizontal position, as will be presently descrbed. In thepresent illustration of my invention I have shownV two of these bracketsconnected by the board or bar E, so that by moving the board thebrackets will be carried therewith and adjustably secured with respectto the wall. Boards in the opposite direction said parts may belowered.The shaft G is here shown as bearing in eyebolts e, although it isobvious that other supports may be employed, and said shaft is' providedatone or both ends with a crank-arm H, whereby said shaft may be manipulated from above, and the shaft is furthermore provided with a pulleyI, fixed thereto to receive an endless rope K, which passes over asimilar pulley L, secured to a shaft M, journaled in the structure nearthe lower end thereof, and also carries a hand-crank N for themanipulation of the same. These shafts G and M are respectively providedwith a 'ratchet-wheel P, and a spring or other suitable pawl Q is fixedat a point on the structure to engage the teeth of said pawls, so as tolock the shafts from turning in one direction, but allow them to turn inan 'opposite direction.

R indicates a clasp or clamp, which is designed to hold theconnecting-board E in position against the wall. This clamp may becomposed of a bar of spring-steel or other suitable material bent, asshown, so that the short branch f may take under the lower edge of oneof the weather-boarding, as shown, and the outer or longer branch g maypress against the face of said board E, so' as 'to .press the sameagainst the studding and last-set board, and this clamp may be providedwith a ring 71. for convenience. By the' employment of this spring-clampit will be seen that the board E will be firmly held against the lastsetboard, as shown, and may be quickly removed and replaced when setting anew board. It will be observed that the board to be set is placed on theupper edge of the connectingboard E in a position overlapping the upperedge of the last-set board where the two are ,nailedtogethen and by thismeans the board IOO E may not only servc as a rest for theweatherboarding, but may also serve as a gage for the set of the boards.

It Will be seen that the inner end of the bar 5 a is provided With ,ametallic strap i, taking boardin` of a structure, ropes suspending saidboard, and suitable means connected With said ropes for adj nstablysnstaining the board and brackets, substantiaily as specified.

The brackets having horizontai branches and legs securcd at t-heir onterends, in combination with the board 'secured to the inner endsof thehorizontai branches of the brackets, the ciamp R, adapted to embrace aWeatherboard and bear against the connecting-board of the bracket, andthe suspending-ropes secnred to said board and secured at their oppositeends to a shaft, Whereby said brackets and board may be adjustedverticaily, substantially as specified.
